About the diameter of a dot made by a ballpoint pen, Semprius’s solar photovoltaic (PV) cells are triple junction cells made of gallium arsenide. Low cost lenses concentrate sunlight 1,100-times onto the cells. Their tiny size reduces module cost as they take up only 1/1000th of the entire solar module area. It also enables a high density of cells per module, which better distributes unwanted heat across the entire solar module solar area. That eliminates the need for heat dissipation hardware, such as heat fins, further reducing production costs.
